The concepts of Topology\, the steps necessary for its implem entation and the benefits for an organization are presented. Finally\, the project is presented where\, from a Plugin developed in Python in QGIS\, the implemented resources and the results obtained are demonstrated. The f ull content of the Project can be viewed in these two articles:\n\n• htt ps://www.linkedin.com/pulse/topologia-de-rede-espacializada-rodrigo-pascho al-do-valle-wx7hf/?trackingId=gNxyrwDYR1ahkTMHJEN%2FzA%3D%3D\n\n• https: //www.linkedin.com/pulse/topologia-rede-de-saneamento-rodrigo-paschoal-do- valle-uxblf/?trackingId=1UOrKCOaQcmffR9BqAnqcQ%3D%3D\n\nInitially\, the co ncepts and steps necessary for the elaboration of Topology will be present ed in a simple and objective way. A Water Distribution Network (Sanitation ) will be used as an example\, as its elements are easy to see. Three main elements will be addressed:\n\n• Segments: representing the distributio n network.\n• Valves: representing the point at which the flow can be in terrupted.\n• Reservoir: representing the starting point of the network (start of supply).\n\nFor each element\, its characteristics (SYNTAX) and behaviors (SEMANTICS) will be presented. The analysis focuses on simplifyi ng the model\, meeting what is necessary for the development of the resour ces that will be explored in Topology.\n\nAfter the contextualization of t he Topology\, some challenges faced during its implementation will be pres ented. Emphasizing the eventual necessary adjustment in the registered ele ments\, as examples:\n\n• Unconnected segments: adequacy of the initial and final vertices to establish the connection.\n• Valves superimposed o n segments: division of the segment and insertion of valve between them.\n • Unconnected reservoirs: adequacy of the segment vertex to establish th e connection.\n\nThe benefits obtained and the ability to increase the mat urity of an organization are addressed\, as static records are transformed into active elements\, enabling maneuvers\, validations and behavior anal ysis. Thus\, we have the development of Network Intelligence. These and ot her benefits will be addressed in preparation for the presentation of the results developed in the Project.\n\nThe project had two stages: In the fi rst\, a Natural Gas Distribution Network was used on which the Network Iso lation mechanism was implemented\; in the second\, a Water Distribution Ne twork was used and new resources were implemented: Network Analysis\, Netw ork Status and Opening and Closing of Valves. The presentation will focus on the advantages obtained by the implemented resources\, demonstrating th e characteristics and applications of each one.\n\nFor the presentation of the implemented resources\, images and videos will be used\, as well as m ade in the published articles.\n\nStep 1: Contextualization of the Gas Distribution case\n• Network Isolation: need to isolate the s ection in an Emergency situation (Leak)\nPresentation of the results and c oncepts involved: Selected Segment\, Isolated Section\, Affected Section a nd Valves to be closed.\n\nEmphasis also on future benefits related to iso lation:\n• Identification of Customers Affected in the maneuvers perform ed.\n• Identification of Critical Regions in which a one-off isolation a ffects a vast region.\n• Analysis of existing resources in a Graph struc ture: (1) identification of critical paths\, (2) analysis of points withou t supply redundancy\, (3) automatic assignment of the status of segments f rom the manipulation of valves.\n• Assistance in Supply Continuity Strat egies\, identifying Critical Customers (such as Hospitals) that are in vul nerable regions.\n\nStep 2: Contextualization of the Sanitation case an d implemented resources\n• Network Analysis: an analysis is m ade on the imported elements to identify inconsistencies\, thus validating the model. The following situations were analyzed: (1) Valves connected t o only one Segment\, (2) Valves connected to more than two Segments\, (3) Segments isolated from the Network\, (4) Segments not connected to Reservo irs\, and (5) Isolated Valves and Reservoirs. This analysis can be expande d\, according to the elements and rules used by Topology\, and can also he lp in estimating the effort required in adjusting records.\n\n• Netwo rk Status: from the connections between Reservoirs\, Segments and Regi sters (open and closed) the points of the Network that are Supplied and No t Supplied are presented. With this functionality\, the status of a certai n stretch is automatically defined\, thus not requiring the intervention o f an operator to update the Network. The feature has the same behavior for Gas Networks\, respecting the elements of Topology.\n\n• Opening and Closing of Valves: after analyzing the Network\, it is possible to se lect the Valves and open/close them\, automatically updating the network. This feature is especially important for situations where we need to analy ze the impact on the Network of maneuvers performed. This feature can be u sed in conjunction with Network Isolation to study the behavior of the dis tribution fabric.\n\nNext steps\n• Include the list of Affected C ustomers in the resources already developed.\n• Explore opportunities fo r new resources\, some with room to be used by any Distribution Network\, others that make sense only for certain contexts\;\n• Use of the model ( BDGD) – Geographic Database of the Distributor\, required by ANEEL (Nati onal Electric Energy Agency) for the delivery of data from the concessiona ires\, including an Electric Energy Distribution Network to the project\;\ n• Prospect any use case related to Telecommunications Networks.\n\nC onclusion\nIn this second example\, the Water Distribution Concessiona ire urgently needed to resupply Hospitals in a certain region of Porto Ale gre. As alternatives were implemented\, a number of houses and buildings a lso had their supply normalized. In this situation\, only critical points should be supplied\, directing the scarce resource only to emergency point s. Network Topology enables this maneuver and the creation of strategies f or network segmentation.
